This guest XML would be expected to fail if the guest is running on a
host that is using qemu w/o kvm acceleration:
<vcpu placement='static' cpuset='0-1'>1</vcpu>
...as qemu does not support pinning when kvm isn't available. What's not
clear to me is why the Ubuntu version would be adding this line since it
sounds like master/kilo-3 is behaving correctly per the spec (only
adding these lines where the user explicitly requests direct pinning of
CPUs on the image or flavor [1]).
